Dry scrubber system with bacteria

A gas treatment system comprising:

• a biological scrubber system configured to flow a gas stream through a bacteria environment to consume acid gas from the gas stream;
• and
• a dry chemical scrubber coupled to an outflow gas stream from the biological scrubber, the dry chemical scrubber including a media to remove acid gas from the outflow gas stream.

A method comprising:

• receiving an input gas stream at a biological scrubber configured to store bacteria to consume acid gas from the input gas stream;
• and
• directing an outflow gas stream of the biological scrubber into a dry chemical scrubber configured to hold media and bacteria that remove acid gas from the output gas stream.

A method comprising:

• injecting bacteria into a dry chemical scrubber configured to hold media and bacteria that remove acid gas from an acid gas stream to provide a reduced acid gas stream;
• and
• directing an acid gas stream into the dry chemical scrubber.
